MOTlVE-FLUlD-SUPPLY DEVICE FOR TRAVELING CRANES.

SPECIFICATION forming part of Letters Patent No. 598,429, dated February 1, 1898. Application filed December 24, 1896. Serial No. 616,898. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES E. MARIS, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Motive-Fluid-Supply Devices for Traveling Cranes, of which the following is a specification.

My invention consists of an arrangement of pipes and connections for supplying motive fluid to the fluid-operated hoists carried by traveling cranes, whereby I am enabled to do away with long runs of hose for conveying the motive fluid, which are objectionable because they soon become worn and useless from being so often bent and twisted by the travel of the crane.

My invention is fully illustrated in the accompanying drawings, in which- Figure 1 is a plan view of my improved arrangement of motive-fluid-supply pipes and connections; and Fig. 2 isa view in elevation of the traveling crane, showing the motivefluid-supply pipes mounted above the same.

Heretofore fluid .has been supplied to the hoistin gcylinders carried by traveling cranes by means of a flexible hose connection supported by hooks on the wall of the building in which the crane was located, or supported by brackets on the crane. As the crane approached the point where the hose was connected to the supply-pipe it was necessary to take up the same and coil or twist it on the crane, and as the crane left this point the hose had to be let out. This twisting or coiling of the hose soon causes it to wear and become leaky and consequently useless. Another plan has been to hang a pipe by a hingejoint from the supply-pipe and to hang another pipe by a like joint from the inlet of the hoisting-cylinder, these pipes being provided with a hinge-joint at their lower extremities. This plan, however, is unsatisfactory because of the hinge-joints and because the weight of the pipes is borne by the crane.

With my improved form of motive-fluidsupply pipes I provide a structure that is at once efficient, simple, and not liable to get out of order.

any suitable manner. A vertical hoisting=- cylinder 13 may be suspended from the crane at b, a pipe I) being connected with the inletpassage of this cylinder. The supply-pipe for the motive fluid is shown at C, C and 0 being the pipes which convey it to the cylinder B. The upper pipe 0' is carried by a swiveled hanger 00, secured to the ceiling of the building or to a bracket projecting from the wall. At its opposite end it is provided with a trolley 50, adapted to a rail x carried by brackets 00 depending from the ceiling. The pipe C carries a swiveled hanger 00 which supports the pipe 0 the hanger being secured to said pipe 0 and free to slide longitudinally on the pipe 0. The other end of said pipe 0 is carriedby a swiveled head D, mounted on the top of thestandard D, secured to the crane. A flexible hose d connects the fluidsupply pipe 0 with the pipe 0. A like hose cl connects the pipes O and O and a hose d connects the pipe (3 with the pipe I), which supplies the cylinder B with the motive fluid.

The rail :0 on which the trolley 00 is adapted to travel, constitutes the arc of a circle the center of which is the pivot-point of the swiveled hanger 00, carrying the pipe C.

Between the hanger m and the connection for the hose cl is interposed a spring g which tends to move said hanger :0 inwardly on the pipe 0, such inward movement being limited by a stop f on said pipe 0.

The first portion of the pull of the pipe 0 after the latter passes the pipe 0 in either direction is mainly inward, and the spring causes the hanger 00 to follow this inward pull until it strikes the stop f, by which time the pipe 0 has been moved so far out of line with the pipe 0 that a sufficient sidewise pull upon the same will be exerted to cause its easy movement.

I claim as myinvention- 1. In motive-fluidsupply devices for trav eling cranes, the combination of the cylinder carried by the crane, a series of horizontal pipes for supplying motive fluid to said cyl inder, one of said pipes being pivoted to a fixed structure independent of the crane, and another pipe being pivoted to the crane, flexi-- ble connecting-sections between the pipes and a pivoted connection for the outer ends of the pipes.

2. In motive-fiuid-supply devices for traveling cranes, the combination of the hoistingcylinder, an upper horizontal motive-fluidconducting pipe, a sWiveled support for the same independent of the crane, a lower'horizontal motiVe-fluid-conducting pipe having a swiveled support on the crane, a slidingand' pivotal connection for the outer ends of the pipes, and flexible connecting-sections between the pipes, substantially as described;

3. In motive-fluid-supply devices for traveling cranes, the combination of the crane, the cylinder carried thereby, horizontal conducting-pipes for the motive fluid located above the cylinder and havingswiveledc'on-' nections, a-flexible connection between said pipes, a railsecured'to a fixed structure" independent of the crane, and a Wheel or trolley carried by one of the pipes andadapted to said-rail.
